Fortunately, this situation does not happen often on my Listserv lists. When it does, I first run an active probe of the list. More times than not, forcing a probe will weed out the errant subscriptions. How to do this is described in the list maintainer's documentation on L-Soft's web site. If a probe does not work, then I extract all the subscriptions in the troublesome list and I write a little perl script that sends an email to each subscriber. This email contains the subscriber's email address in the subject line as well as the body. I put the address in both locations because sometimes the bounces mangle the subject. If they mangle the subject and the body of my test message, then I just ignore the situation. Fortunately, this kind of drastic action is rarely needed.
